Works covered by copyright (listed). All are creative and original works.

Creative Commons is a non-profit organization that offers their own set of licenses that work alongside traditional copyright: “Our free, easy-to-use copyright licenses provide a simple, standardized way to give the public permission to share and use your creative work — on conditions of your choice. CC licenses let you easily change your copyright terms from the default of “all rights reserved” to “some rights reserved.”

Public Domain: Public Domain content is “free from barriers to access or reuse usually associated with copyright protection.” This comes into effect when copyright runs out but you can also voluntarily remove barriers to access your work.

How to license your work for Public Domain: You can freely license using the GNU Free License or the Free Art License.

Slide 7: Anonymity: You can also give up claim to authorship/ownership of work, which will most likely put it into the Public Domain (unless it is part of a larger collection, owned by another organization, etc.)
